Nine miles long and forty-five wide, the island is home to three distinct types of woodland. It's waters have seen ten major shipwrecks since 1877 - several of them accessible to scuba divers. The island also has four lighthouses -- three of them built before 1900 -- the oldest being The Rock Lighthouse, which was put into use in 1855.

Isle Royale is probably our most isolated National Park; vistors can only get there by seaplane or boat. For that reason it is also one of our most pristine.
